I'm not particularly interested in products that combine two or more other products into one, but a project like this that is coming up on 8 mil is interesting, and with 29 days left! (It actually reminds me of the movie Father of Invention with Kevin Spacey. =) Not interested in the cooler, but impressed on what he has pulled off.
He's got the website coolestkickstarter.com, which may or may not have been completely built the first time around as the first blog post appears to be in 2014, after it ended the first time around. He also has another business called
http://www.inventorsblueprint.com/ which looks like he started in 2011, which also has a blog that helps other inventors. He's definitely got an audience, but still doesn't explain the difference between 100k and 8mil and counting. I'd probably just assume that he gathered his audience the first time around, then on second launch, those same backers came back. In addition, I think people are more likely to back a project that already has momentum. The rest is hype.
